Abstract (en)
A manufacturing method of a bicycle wheel hub includes pre-weaving into a carbon fiber sleeve (10), stacking and telescoping carbon fiber sleeves, placing into left and right molds (30,31), placing reinforcing sheets (20), clamping upper and lower molds (32,33), vacuuming, injecting a resin, curing, mold opening and drilling. A structure of the wheel hub manufacturing by the method includes a carbon fiber body (40) and two reinforcing sheets (20). The carbon fiber body includes a tube portion (41) and two ear portions (42), which are integrally extended from two ends of the tube portion and have the larger outer diameters. The ear portions have spoke holes (43) arranged separately and in a ring shape. The reinforcing sheets are ring-shaped sheets and covered in the two ear portions, respectively, when the carbon fiber body is formed. The reinforcing sheets have through holes, which correspond to the spoke holes and have the same shape. The manufacturing method and structure has the enhanced production efficiency, stable quality, low cost and high structural strength.
